My scriptures say the same about yours. Buddhist scriptures tells of a creator god (who actually created this earth) to have fallen under the spell of Mara (the deceiving angel) who feigns to serve at this God's court and is deceived into thinking of himself as the supreme being. So Buddha had to ascend to the heavens to counter this. The interesting thing here is that in the Bible, the Satan is actually at the court of YhWh and appears to work for him too (at least till Jesus's time when he is expelled or something). So it is quite possible that YhWh is the Creator God being discussed by Buddha here. Here is the Sutta
Brahma-nimantanika Sutta: The Brahma Invitation
Basically the Creator God had come to believe (under the influence of Mara) that He is the Supreme and His realm is the final realm. That he is Omnipotent. Buddha corrects him, shows many beings and realms exist above him and that the final state is the state at which Buddha is, the Unbound state described as "Consciousness without surface, endless all-encompassing and radiant" . Buddha also says many beings do worship this Creator God and hence fall under his power, but he and his disciples as well as the higher beings are beyond the God's reach.
